ABSTRAK
Pelaksanaan proyek konstruksi memiliki batas waktu (deadline) yang telah
ditetapkan sesuai dengan dokumen kontrak yang telah disepakati. Pada tahap
pelaksaanaan biasanya sering timbul kendala, baik kendala yang sudah
diperhitungkan maupun kendala yang terjadi diluar perhitungan. Berbagai kendala
tersebut dapat mengakibatkan timbulnya permasalahan seperti penundaan (delay)
dan keterlambatan pada penyelesaian proyek konstruksi.
Penelitian ini dilakukan sebagai upaya untuk mendapatkan dan mengetahui
faktor-faktor penyebab keterlambatan proyek konstruksi dan subfaktor yang
mempengaruhi pada masing-masing faktor keterlambatan. Penelitian ini dilakukan
dengan cara wawancara dan menganalisis schedule di proyek Fine Yarn III
Building, Tangerang.
Hasil penelitian menunjukkan bahwa faktor-faktor dominan penyebab
keterlambatan pada proyek Fine Yarn III Building adalah faktor perubahan desain
yang terjadi pada perubahan gambar desain pondasi. Faktor karakteristik tempat
yaitu kondisi dibawah permukaan tanah. Faktor situasi yaitu intensitas curah
hujan. Faktor bahan (material) yaitu keterlambatan pengiriman barang import
yaitu aksesoris pipa-pipa. Faktor pekerja yaitu jumlah pekerja pasang bata kurang
memadai. Waktu keterlambatan yang dialami pada proyek Fine Yarn III Building
adalah 1,5 bulan atau 6 minggu. Keterlambatan yang signifikan terjadi pada
aktivitas pekerjaan Pile Cap dan Tie Beam.
Kata Kunci: Faktor Dominan, Waktu Keterlambatan, Jenis Pekerjaan.

ABSTRACT
Construction projects execution have a deadline that be appointed in agreed
contract document. In execution phase usually occurs constrains, either the
excpected or the unexpected constrains. The constrains may cause problems such
as delay in completion of the construction project.
This research was conducted as an effort to get and know the factors delays and
the subfactors that influence each delay factors. This research was conducted by
interview and schedule analyze at Fine Yarn III Building project, Tangerang.
The research result showed that the most dominant factors and subfactors causing
delays are scope and contract/work document factor with foundation drawing
design change, site characteristic factor with soil condition below the ground
surface. Site situation factor with rainfall intensity. Material factor with delay of
import pipes material accessories delivery. Labors factor with insufficient brick
workers. The delay time in Fine Yarn III Building project is one and a half month
or six weeks. The significant delay occurs in Pile Cap and Tie Beam work
activity.
